Hooked up Boost guage the other day and am reading 11 pounds of boost at full throttle which I know isnt right. Stock pulley and I got the gauge because I think I'm actually running alittle low on boost. Anyway can anybody tell me the right place to plug in boost line to supercharger is it the one the comes out the back of the charger towards the firewall or the one on the bottem plate facing straight up at the back of the charger right beside the map sensor

Thanks for any help

 

I hooked my boost/vac sensor up to the one facing straight up beside the Map sensor line. Just needed to do a little piping since the map sensor tube is very close to the other port. Mine is a MP122.

 

facing up.

 

the small brass pipe fitting facing straight up on the driver's side of the rear of the manifold for the M112 supercharger (if that is what you have)
